Reported are the results of a survey of 98,000 engineers taken to be representative of approximately 500,000 members of engineering societies. Data analysis was done on 59,200 usable questionnaires. The list is believed to have included about 40 percent of the engineers in the nation. A facsimile questionnaire is reproduced at the end of the report. Included in the data are highest degree, age, employment status, curriculum of highest degree, sex, citizenship, degree year of first degree, type of employer, field of specialization, product or service area, area of technology, job function, and geographic location. The data are reported, where appropriate, for 1970 and 1971. This survey was conducted for the National Science Foundation. (TS)
